Cetrimide Broth is used for the selective cultivation of Pseudomonas aeruginosa. Pseudomonas aeruginosa grows well on all normal laboratory media. Cetrimide Broth Base is the modification of the formula designed by King, Ward and Raney and is useful for the cultivation of P. aeruginosa. This medium is selective as it contains cetrimide (Cetyl trimethyl ammonium bromide), which inhibits other bacteria except P.aeruginosa. This medium is therefore, important in the identification of P. aeruginosa. Cetrimide Broth is used for the examination of cosmetics and clinical specimens for the presence of P. aeruginosa, as well as for evaluating the efficacy of disinfectants against this organism. Peptic digest of animal tissue and beef extract provide necessary nutrients. Cetrimide acts as a quaternary ammonium, cationic detergent that causes release of nitrogen and phosphorus from bacterial cells other than Pseudomonas aeruginosa. Sodium chloride maintains osmotic equilibrium in the medium.
